A powered Hub is a separate ~$20 component that you plug into one of your USB ports, that also has an external power supply to give it more current capacity. The 2x2, 4x4 MIDIPorts draw just a bit too much current for a standard USB port. Check your local computer store. They'll know exactly what a Powered USB Hub is.

Even without using all the usb ports it is necessary.

I recall someone on this list talking about the purchase of some type of power unit to assist these devices. (1) is there such an animal? (2) is it possible that the unit is starting to go? (3) could it be something with the usb ports on the computer, although I used all of them? Thanks in advance. ----- Original Message ----- From: Neal Ewers To: midimag@xxxxxxxxxxx Sent: Friday, November 05, 2010 1:56 AM Subject: RE: [midi-mag] correction on Olympus recorder marks being seen by other audio editors Sarah, yes, Oh that the Olympus did what the H1, h2, h4 and h4n recorders do. All their marks are seen by other recording software. So too with the Sony PCM-D50. This is one thing that Olympus does that makes you think that they still largely think about it as a dictation and transcription technology where internal marks would help you get to parts of the dictation. I don't know what it would take to have these recorders drop real marks, but the ones I have seen do not.

" You can drop marks while playing and/or recording, and, in wave anyway, editors like SoundForge and others will recognize them as such." Oh, how I wish this were true, but it is not. These marks are only internal to the Olympus units and thus can only be gotten to while using the recorders.
